Most of the nodes of exynos5420 remains same for exynos5800.
So the exynos5420.dtsi is included in exynos5800 and the changed

Pull vfs dcache livelock fix from Al Viro:
"Fixes for livelocks in shrink_dentry_list() introduced by fixes to
shrink list corruption; the root cause was that trylock of parent's
->d_lock could be disrupted by d_walk() happening on other CPUs,
resulting in shrink_dentry_list() making no progress *and* the same
d_walk() being called again and again for as long as
shrink_dentry_list() doesn't get past that mess.
The solution is to have shrink_dentry_list() treat that trylock
failure not as 'try to do the same thing again', but 'lock them in the
right order'"

Call pcie_bus_configure_settings() on ARM, like for other platforms.
pcie_bus_configure_settings() makes sure the MPS across the bus is uniform
and provides the ability to tune the MRSS and MPS to higher performance
values. This is particularly important for embedded where there is no
firmware to program these PCIe settings for the OS.

We have the same problem with ->d_lock order in the inner loop, where
we are dropping references to ancestors. Same solution, basically -
instead of using dentry_kill() we use lock_parent() (introduced in the
previous commit) to get that lock in a safe way, recheck ->d_count
(in case if lock_parent() has ended up dropping and retaking ->d_lock
and somebody managed to grab a reference during that window), trylock
the inode->i_lock and use __dentry_kill() to do the rest.

The cause of livelocks there is that we are taking ->d_lock on
dentry and its parent in the wrong order, forcing us to use
trylock on the parent's one. d_walk() takes them in the right
order, and unfortunately it's not hard to create a situation
when shrink_dentry_list() can't make progress since trylock
keeps failing, and shrink_dcache_parent() or check_submounts_and_drop()
keeps calling d_walk() disrupting the very shrink_dentry_list() it's
waiting for.
Solution is straightforward - if that trylock fails, let's unlock
the dentry itself and take locks in the right order. We need to
stabilize ->d_parent without holding ->d_lock, but that's doable
using RCU. And we'd better do that in the very beginning of the
loop in shrink_dentry_list(), since the checks on refcount, etc.
would need to be redone anyway.
That deals with a half of the problem - killing dentries on the
shrink list itself. Another one (dropping their parents) is
in the next commit.
locking parent is interesting - it would be easy to do rcu_read_lock(),
lock whatever we think is a parent, lock dentry itself and check
if the parent is still the right one. Except that we need to check
that *before* locking the dentry, or we are risking taking ->d_lock
out of order. Fortunately, once the D1 is locked, we can check if
D2->d_parent is equal to D1 without the need to lock D2; D2->d_parent
can start or stop pointing to D1 only under D1->d_lock, so taking
D1->d_lock is enough. In other words, the right solution is
rcu_read_lock/lock what looks like parent right now/check if it's
still our parent/rcu_read_unlock/lock the child.

Currently blk-mq registers all the hardware queues in sysfs,
regardless of whether it uses them (e.g. they have CPU mappings)
or not. The unused hardware queues lack the cpux/ directories,
and the other sysfs entries (like active, pending, etc) are all
zeroes.
Change this so that sysfs correctly reflects the current mappings
of the hardware queues.

Firstly, it isn't necessary to hold lock of vblk->vq_lock
when notifying hypervisor about queued I/O.
Secondly, virtqueue_notify() will cause world switch and
it may take long time on some hypervisors(such as, qemu-arm),
so it isn't good to hold the lock and block other vCPUs.
On arm64 quad core VM(qemu-kvm), the patch can increase I/O
performance a lot with VIRTIO_RING_F_EVENT_IDX enabled:
- without the patch: 14K IOPS
- with the patch: 34K IOPS

add_pcie_port() is called only from exynos_pcie_probe(), which is annotated
with __init. Thus it makes sense to annotate add_pcie_port() with __init
to avoid the following section mismatch warning:
WARNING: drivers/pci/built-in.o(.text.unlikely+0xf8): Section mismatch in reference from the function add_pcie_port() to the function .init.text:dw_pcie_host_init()
The function add_pcie_port() references
the function __init dw_pcie_host_init().
This is often because add_pcie_port lacks a __init
annotation or the annotation of dw_pcie_host_init is wrong.

ION system heap keeps pages in its pool for better performance. When the
system is under memory pressure, slab shrinker calls the callback
registered and then the pages pooled get freed.
When the shrinker is called, it checks gfp_mask and determines whether
the pages from highmem need to be freed or the pages from lowmem.
Usually, slab shrinker is invoked on kswapd context which gfp_mask is
always GFP_KERNEL, so only lowmem pages are released on kswapd context.
This means that highmem pages in the pool are never reclaimed until
direct reclaim occurs. This can be problematic when the page pool holds
excessive amounts of highmem.
For now, the shrinker callback cannot know exactly which zone should be
targeted for reclamation, as enough information are not passed to. Thus,
it makes sense to shrink both lowmem and highmem zone on kswapd context.

Merge "omap dt fixes and and clocks for v3.16 merge window" from Tony Lindgren:
Most likely the last pull request from me for omap changes for
v3.16 that's dts fixes for clocks and enabling few features
that were still being discussed earlier:
- A bunch of omap clock related dts fixes queued by Tero Kristo.
- Enable parallel nand on am437x that was not merged earlier as
I requested more information about the muxing for it. And
we need to also enable ecc hardware support for am43xx.
- Enable the modem support for n900 that was dropped earlier
because we had to fix the related hwmod entry first with patch
ARM: OMAP2+: Fix ssi hwmod entry to allow idling.
- And finally, add the omap2 clock dts files. These will allow
us to enable the dt clocks and drop the legacy clocks for omap2
with a follow-up patch once the related clock driver binding
changes are merged.

In (c7d44a02a serial_core: Commonalize crlf when working w/ a non open
console port) the core was modified to make the UART poll_put_char()
automatically convert LF to CRLF. This driver's poll_put_char() adds a
CR itself and this was not disabled by the above patch meaning
currently it sends two CR characters.
The code to issue a character is shared by the console write code (where
driver must do LF to CRLF conversion, although it can make use of the
uart_console_write() helper function) and the poll_put_char (where
driver must not do the conversion). For that reason we add a flag rather
than simply rip out the conversion code.
